[Correlation of cutaneous reactivity between allergenic extracts of Dermatophagoides pteronyssinus and Dermatophagoides farinae with Blomis tropicalis in patients with allergic rinitis and asthma].

Background: There are documented molecular homologies between mites from the same group, but intergroup characteristics are not. Although mites share the same taxonomic order, there are species antigenically distinct. At the present we dont know clearly the differences in cutaneous reactivity among several house dust mites species.
